Answer:

£65.10

Step-by-step explanation:

42*8 = 336

10% = 33.6

14*15 = 210

10% = 21

5% = 10.5

31.5 +33.6 = £65.10

stiks02 [169]

Answer:

The next time Mahnoor visits the restaurant, there is:

--31 % chance for country music

--47% chance of rock & roll

--22% chance of blues

Completed question;

Mahnoor randomly selects times to walk into a local restaurant and observe the type of music being played. She found that the restaurant was playing country 11 times, rock & roll 17 times, and blues 8 times. Use the observed frequencies to create a probability model for the type of music the restaurant is playing the next time Mahnoor walks in.

Step-by-step explanation:

Given;

The number of times they were playing each type of music;

Country = 11 times

Roll = 17 times

Blues = 8 times

Total visits of Mahnoor = 11+17+8 = 36

Developing a frequency table and probability model for the type of music the restaurant is playing the next time Mahnoor walks in.

Probability = number of favourable outcomes ÷ total number of outcomes.

Music played  |  Frequency  |  Probability

country            |  11                 |  11/36 = .31 or 31%

rock & roll        |  17                |  17/36 = .47 or 47%

blues                |  8                 |  8/36 = .22 or 22%

Andrej [43]

Answer:

0.23328,2.4

Step-by-step explanation:

Given that an airport limousine can accommodate up to four passengers on any one trip. The company will accept a maximum of six reservations for a trip, and a passenger must have a reservation.

Assuming independence we can say persons who do not show up is binomial with p = 0.4 and n = 6

a) If six reservations are made, what is the probability that at least one individual with a reservation cannot be accommodated on the trip

= P(X\leq 1)\\=0.23328

b) Expected no of available places = E(x)=np = 6(0.4) = 2.4
